Note: in the table 2, the meaning of 2160 hours in the salt spray resistance test is 2160 hours, the paint film has no crack and no bubble, and so on; 720 hours in comparative example 1 were observed, and the surface color became dark;
as can be seen from Table 2 above, compared with the test results of test example 6, the test results of test examples 1-5 showed better test performances when the particle sizes of the selected zinc powder, titanium powder and zinc oxide were within the range of 5-10 nm; when the grain sizes of the zinc powder, the titanium powder and the zinc oxide which are selected in a combined mode are all 5nm, the salt spray resistance of the obtained coating is remarkably improved, the 3000-hour salt spray resistance effect can be achieved, the drawing force test data of the coating is improved to a certain extent, the drawing force test data of the coating reaches 19.5MPa, and the test result is optimal. In comparative example 1, no zinc oxide addition was found to lead to a gradual darkening of the paint film after 720 hours, indicating a significant reduction in the ageing resistance of the paint film and a reduction in the results of the drawing test. The comparative example 2 does not adopt titanium powder, so that the drawing test result is obviously reduced, the comparative examples 3-4 obviously weaken on the salt spray resistance, and the comparative example 5 adopts other methods for preparation, and the results show that the salt spray resistance, the hardness and the drawing test data are obviously reduced.
Example 2
The nano zinc-plating anticorrosive paint provided by the test example 5 is selected and constructed according to the following construction process:
1) curing: mixing and stirring the component A and the component B for 10 minutes at the stirring speed of 200 revolutions per minute, and filtering the cured coating by 300-mesh filter cloth;
2) roll coating: the surface of the workpiece is kept clean, the cured coating is uniformly coated on the surface of the workpiece from top to bottom by a medium-haired roller in a roller coating mode until the required thickness is achieved.
The paint properties at different film thicknesses were tested and the test results are shown in table 3:
TABLE 3
It can be seen that the drawing data is 13.5MPa and the performance is the best when the film thickness is 133 μm by the roll coating method.
Example 3
The nano zinc-plating anticorrosive paint provided by the test example 5 is selected and constructed according to the following construction process:
1) curing: mixing and stirring the component A and the component B for 10 minutes at the stirring speed of 200 revolutions per minute, and filtering the cured coating by 300-mesh filter cloth;
2) spraying: the surface of the workpiece is kept clean, the surface of the workpiece is uniformly sprayed by adopting a cross spraying method, then the workpiece is placed at normal temperature for 2-3 minutes, and the workpiece is sprayed again until the required thickness is reached.
The paint properties at different film thicknesses were tested and the test results are shown in table 4:
table 4:
therefore, by adopting the spraying method, the film thickness error is small and uniform, the drawing data is higher, and the overall performance is good.
Example 4
The nano zinc-plating anticorrosive paint provided by the test example 5 is selected and constructed according to the following construction process:
1) curing: mixing and stirring the component A and the component B for 10 minutes at the stirring speed of 200 revolutions per minute, and filtering the cured coating by 300-mesh filter cloth;
2) brushing: the surface of the workpiece is kept clean, and the cross brushing method is adopted to uniformly brush the surface of the workpiece to the required thickness in a cross manner.
TABLE 5
From the test results of examples 2-4, tables 3-5, it is seen that the spray results are best, the coating films obtained by spraying are relatively uniform in thickness, the pull-out test index is higher, and the salt spray resistance test time is longer.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
